Benefits of technology

[0030]An exemplary embodiment provides a voltage measuring apparatus having no high voltage switching elements and the battery management system including the same. Accordingly, the size and the size of the voltage measuring apparatus can be reduced, and the battery management system including the voltage measuring apparatus is provided.

Problems solved by technology

The high voltage switching elements have a larger size or a higher cost as compared with other type switching elements.
Accordingly, the size and the cost of the voltage measuring apparatus are increased.

Embodiment Construction

[0036]In the following detailed description, only certain exemplary embodiments have been shown and described, simply by way of illustration. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification.

[0037]Throughout this specification and the claims that follow, when it is described that an element is “coupled” to another element, the element may be “directly coupled” to the other element or “electrically coupled” to the other element through a third element. In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of any other el...

Abstract

Disclosed are a voltage measuring apparatus and a battery management system including the same. The voltage measuring apparatus is connected to a plurality of battery cells connected to each other in series to measure respective voltage of the battery cells. The voltage measuring apparatus includes a first node coupled to one of an positive electrode and a negative electrode of one of a plurality of battery cells as a voltage measuring target, amplifies a voltage difference between the first node and the second node to generate an error voltage, converts the error voltage into a digital signal, and compensates for a polarity of the digital signal.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2013-0020099 filed in the Korean Intellectual Property Office on Feb. 25, 2013, the entire contents of which are incorporated herein by reference.BACKGROUND[0002](a) Field[0003]An exemplary embodiment relates to a voltage measuring apparatus and a battery management system including the same.[0004](b) Description of the Related Art[0005]A voltage measuring apparatus according to the related art for measuring a plurality of battery cell voltages includes a switching unit for changing a polarity of a voltage received from a battery cell. The voltage measuring apparatus according to the related art includes a capacitor for storing voltages received from a plurality of battery cells.[0006]When a plurality of battery cells are sequentially connected to the capacitor, a polarity of the voltage stored in the capacitor is alternately changed. The switching unit...
